SUMMARY
Context. Research of a Reed-Solomon codes characteristics for estimation of code and communication channel parameters influence at the reliabilityand efficiency of information transmission between of control systems devices are performed. The research object is encoding with usingnonbinary redundant Reed-Solomon codes, the research subject is the theoretical and experimental studies of relation between the Reed-Solomoncodes characteristics and their parameters and transmission channel properties. The purpose is characteristics and properties relation analysis for theirusing within encoding and decoding procedures at software of control systems devices.Methods. The math methods and Reed-Solomon codes building theory are used. The formulas for information transmission reliability estimationwith using Reed-Solomon codes taking into account of code character and individual data bits distortions are received. The dependencies of correcttransmission probability from the code and transmission channel parameters are researched. The dependencies of efficiency indicators (informationrate) of transmission with using the Reed-Solomon codes from code parameters are received and researched. The simulation of control system withusing selected method of the noise stability encoding is done. The encoding and decoding procedures for their adaptation and using within controlsystems devises software are realized.Results. The dependencies of the Reed-Solomon codes reliability indicators (correct transmission probability) and the efficiency indicators (informationrate) from its parameters (Galua field module, number of corrected errors, code shortening degree) are received. The recommendations forusing results for code parameters selecting are done. The control system model with using MathWorks MatLab Simulink is created and configured.The software modules with encoding and decoding procedures for their practical realization within embedded software of control systems devices aredeveloped.Conclusions. The performed research illustrates the dependence of the reliability and efficiency indicators of information transmission from theReed-Solomon codes parameters. This allows design reliable control systems with preset level of reliability than provided by a reasonable selection ofReed-Solomon code parameters
